Layer Cake 10" Square HST Tutorial

The love of half square triangles strikes again!
This one is quick as well as easy. I used 10 squares and made 40 hsts and 4 squares in 25 minutes, without rushing!

Layer (2) starched 10" squares right sides together.

Stitch 1/4" down two parallel sides.

Cut on the diagonal, from corner to corner.


Press open.

Lay two triangles, these are one half of a quarter square triangle, right sides
together and stitch along the long edge.

Press open.

Trim. 13" = 3.25" patches, 12" = 3" patches.

Cut a 4 x 4 grid. (For 12", cut at 3", 6", & 9" both across and up/down)

Voila! 8 a/b half square triangles and 4 fabric a & 4 fabric b 3" squares.


Cool...now what can I make?

A/ One layer cake, 42 10" squares = 168 3" hsts, and 168 3" squares, which is 336 patches or a quilt laid out 17*19 rows is 43"*48".

B/ One layer cake & background/solid layer cake = 336 hsts, 168 print & 168 solid squares, which is 672 patches, laid out 25*26 rows is 63"x65.5"

If using from 13", instead of 3", it is 3.25" patches, making A/48*53 & B/ 69"*72.
